Blood Gender Test- Has it been wrong for anyone?

[hyoung]

I received my results from my 12 weeks gender dna test in two business days. My office offered it free since I was having the genetic scan. Was hoping for a girl but it is saying boy. I have all boys and was wondering if anyone has had inaccurate results from this?

Which test is it? MaterniT21 is accurate. Most of the new DNA tests should be accurate.

I'm not sure. They didn't tell me. I had it done at the Center of Medical Genetics in Houston.

It is probably accurate. Did it also test the 13,18,21 chromosomes?
